validating at least one checkbox is selected

I'm trying to validate that at least one checkbox in the form has been checked, however it's not currently working.

This is what my controller looks like: 

class UserExpertise < ActiveRecord::Base
  belongs_to :user
  validate :atleast_one_is_checked

  def atleast_one_is_checked
    errors.add(:base, "Select at least one expertise") unless :gardening || :cooking || :cleaning || :washing_up
  end
end

However, no error shows up when none of them are selected. Incidentally, if instead I were to remove the 'unless' portion of the code, as follows, an error shows all the time, regardless of how many or how few are selected. 

  def atleast_one_is_checked
    errors.add(:base, "Select at least one expertise") 
  end
end

I can't get validation that at least one checkbox has been selected though, as the above does not seem to work. Any help would be appreciated!

:gardening, :cooking, :cleaning and :washing_up are symbols here, they're treated by the conditional statements as true values. Use methods related to the attributes, just:

def atleast_one_is_checked
  errors.add(:base, "Select at least one expertise") unless gardening || cooking || cleaning || washing_up
end
